DIRECT-INDIRECT HEATING AND VENTILATING APPARATUS.

Application filed July 29, 1922. Serial No. 578,308.

To all whom it may concern:

Be it known that I, THOMAS F. OI-InunoN, a citizen of the United States, and a resident of Terre I-Iaute, county of Vigo, and State of Indiana, have invented a certain new and useful Direct-Indirect Heating and Ventilating Apparatus; and I do hereby declarethat the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

The object'of this invention is to provide improved heating and 'entilating apparatus for public schools and other public and private buildings, of the direct-indirect radiator type.

One feature of the invention consists in a casing readily insertible and removable which surrounds all or a part of a radiator and with the top open andwith an opening on one side at the lower end coinmunicating with a louver admitting outside air and on the other side at the lower end an opening communicating with the room, a vertically sli-dably damper for closing each of said openings, and means for simul taneously moving and alternately opening and closing said two dampers, whereby when one is closed, the other is open and the dampers can be easily opened to equal or varying degrees.

Another feature of the invention consists in the means for securing said apparatus in place readily on aradiator and for operating said dampers.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Figure 1 is a perspective view of the apparatus as a whole. Fig. 2 is a front elevation of, the same apparatus with a portion of the casing on one side broken away. Fig. 3 is a central vertical section through the apparatus showing the.

outside damper open and inside damper closed. Fig. 4 is the same showing the dampers reversed and showing the section through the wall containing the louver or outside air inlet chamber. Fig. 5 is a horizontal sect-ion through the apparatus on the line. 5-5 of Fi 3.

In the drawings there is a radiator 10 located on the floor 11 of a rooinhavingan outside wall 12 in which a louver 18, of the usual type, is located, for admitting fresh air from the. outside into the room. The radiatormay be ofanyof the well known forms. The important use of such invention as is here set forth is inthe heating and ventilation of school rooms and other public buildings. 7 I I The invention resides in the combination with a radiator and louver of the additional apparatus shown in Figs. 1, 3 and 5, which isadded to the radiator, as indicated in Fig. 1. There is a rectangular casing having four vertical guide bars 20, one in each corner, as shown in Fig. 5, in which dampers 21 and 22 are located and vertically slidable. In the lower part at each side of the casing there is a rectangular plate 23 secured by bolts 24. One plate 23 is located next to the louver and has a damper opening 25 communicating with the passage through the louver and opposite thereto. The other plate '23 has an opening 26 into the room and these openings, the inlet and outlet, are closed or regulated by the dampers 21 and 22. The plates provided with these damper openings are located at the opposite sides of the radiator adjacent the floor -11 of the room and, therefore, beside the lower part of the radiator.

There are end plates at the lower part of said casing formed of a plate 30, which is bolted at each end to the plates 23 and having an end recess, whereby it can be inserted between radiator sections and over the union 31 of the radiator sections. A plate 32 is inserted in the opening in the plate 30 to completely close the end of the lower part of the casing. "The "outer end of said plate 32 or left-hand end, as shown in Figs. 3 and 4, is laterally angled and securedby bolts to the plate 23 and the upper and lower edges of the plate 32 are widened where it fits adjacent the edges of the opening in said plate 30.; This construction enables the device to be mounted in connection with. a radiator, as shown in Fig 1, or removed therefrom, as desired.

A suitable sheet 35,, formed of sheet metal, is secured, to the outside of the casing above the plates 23and extends almost to the top of the radiator and has inwardly extending ends projecting between radiator sections, as shown in Fig. 1. There are two sheets 85, one on each side of the radiator, that cooperate to complete the casing and the inwardly extending portions, near their upper'ends, are cut away so as to fit around the upper unions of the radiator sections. These two casing sheets 35 are bolted to the bars 20.

The casing thus formed surrounds the radiator or desired portion thereof, but with the upper end open so that the air can pass upwardly through the radiator and become heated and pass out into the room.

The dampers 2land 22 are connected and operated simultaneously and so that when one is entirely open, the other is entirely closed, as seen in Figs. 3 and' i. Means for accomplishing this object is a sprocket chain 40 attached to the upper part of each damper near the middle thereof and extending over a sprocket wheel ll slidably secured on a rectangular rod 42 that extends horizontally through the openings in the radiator, as shown, and the rod 42 is supported by hook bars 43 caught over the interlocking lugs 4st of adjacent sections of the radiator or any other construction connecting the adjacent radiator sections. The rod is held from longitudinal movement by a disk 46 which is slidable on said rod and secured thereto by a set screw 4'7. The rod extends outside of the radiator and has a hand wheel 48 thereon for turning thesame.

In mounting the structure shown in Fig. 3 on a radiator, the two sides of the casing are separately assembled. The side next to the wall, as shown in Fig. 4:, when assembled, contains the two uprights 20, the damper plate 23, and plate 30 at the lower end. The other side of the casing contains the two corner uprights 20 and the damper plate 23 at the lowerend. Then the two halves, as it were, of the casing or structure, are put in place, one at each side of the radiator, so that the plates 30 will extend over the unions 31. Then the plates 32 are fastened in place and the shaft 42 is inserted in the radiator through round holes provided in the two hanger bars 44:, and as it is inserted the disk 46 and the sprocket wheel 41 are held in place between the de sired radiator sections so that the rod 412 can be inserted through them, and the chain is then put in place, after which the sheet metal members 35, of the casing are located, the lower edges thereof fitting in suitably provided seats between the ends of the end plates 30 and the upper edges of the damper plates 23, as shown ;in Figs. 3 and i.

I The chain l0 is of such lengththat when one damper -isopened,-the other is closed, as shown in Figs. 3 and 4. 'Therefore, when the device is located, as seen in Fig. 3, the incoming air from the outside passes up through the radiator into the room. When thedampers afre reversed,;as shown-in Fig. 4,

the cooler air fr'om theroom enters through the damper open ng 26 and passes up through the radiator and discharges into the the radiator to a point near the top of the radiator; and there is on its upper end a plate 51 on which are the words Shut Half and Open arranged from top to the bottom, in the order named, and said plate reciprocates in astationary hood 5 2 which is secured to the top of the rear sheet K 35 of the casing and has about midway thereof an aperture 53 through which one of said words is visible, depending upon the posh tion of the rear damper. When said damper is half-closed, the word Half is disclosed through the opening. When the rear damper is down or closed, the word Shut will be disclosed through said opening and when the rear damper is open to the limit, the word Open will appear in said opening 52.

In order to direct the draft upward through the radiator when both dampers are open partially or equally and direct the di= rect passage of cold air from theoutside into the room, a deflector 60 is located in the lower part of the structure, being pivoted on a damper rod 61 in the end walls 30 of the casing and curved downwardly and rearwardly with the lower end resting on the floor. lVhen the front damper 22 is entirely open, as in Fig. 4, the damper 60 will not interfere much with the cold air coming from the room and passing up through the radiator and being heated. But when the two dampers 21 and 22 are both open, say equally, theincoming cold air through opening damper 25 will be deflected upwardly by the damper 60. Said damper hangs loosely so the free end can be elevated for cleaning beneath theradiator.

The invention claimed is:

1. Direct-indirect heating and ventilating apparatus including, in combinaton with a radiator and a louver at the lower end of the radiator, a casing surrounding the radiator with the top open and with an opening at the lower end communicating with the louver and another opening at the side opposite the louver, a damper for controlling each of said openings, a hand-operated rod extending into the radiator, removable hook bars carried by the radiator for supporting said rod, a sprocket wheel between, two sec tions of-the radiator-through which said rod is insertable and arranged to be turned by said rod, removable means for preventing the longitudinal displacement of said rod and a chain operated by said sprocket wheel and connected with said dampers so that it will simultaneously open one damper and permit the other damper to close. I

2. Direct-indirect heating and ventilating apparatus including, in combination with a radiator and a louver at the lower cud of the radiator, a casing surrounding the radiator with the top open and with an opening at the lower end communicating with the louver and another opening at the side opposite the louver, a damper for controlling each of said openings, a hand-operated rod extending into the radiator, removable hook bars carried by the radiator for supporting said rod, a sprocket wheel between two sections of the radiator through which said rod is inscrtable and arranged to be turned by said rod, a disk located between two adjacent sect-ions of the radiator through which said rod is insertable, a set screw for holding the disk on the rod in order to pre vent longitudinal displacement of the rod and a chain operated by said sprocket wheel and connected with said dampers so that it will simultaneously open one damper and permit the other damper to close.

3. Direct-indirect heating and ventilating apparatus including, in combination with a radiator and a louver at the lower end of the radiator, a casing surrounding the radiator with the top open and with an opening at the lower end communicating with the louver and another opening in the side opposite the louver, a damper for controlling each of said openings, means for simultaneously operating said dampers and arranged so that one damper will close as the other damper is being opened, and a deflector extending longitudinally of the device and loosely pivoted to the ends of the casing near the front and near the middle of the opening to the room and curved downwardly and rearwardly to thefloor for deflecting the air coming through the louver upwardly through the radiator when both dampers are partially opened.

In witness whereof, I have hereunto atfixed my signature.
